  • Q1

    Stars that are relatively close can be distinguished from stars that are much farther away by making observations at different times during the year. This is because -

    coser stars will change a lot in size, while more distant stars appear the same size.

    more distant stars always appear to be the same color, but closer stars change color.

    more distant stars move more quickly through the sky in some seasons than closer stars.

    closer stars will appear to shift more in relative position compared to more distant stars.

  • Q2

    The portion of the electromagnetic spectrum that transmits thermal energy and is sometimes used to cook food or keep it warm is the wavelength known as–

    X-rays.

    gamma radiation.

    radio waves.

    infrared radiation.

  • Q3

    Astronomers make observations in visible light, but also in other parts of the electromagnetic spectrum, such as radio and gamma waves. Scientists make observations in different wavelengths because -

    the information provided by visible light is not a reliable source of data.

    the equipment required for observations in other wavelengths is expensive.

    visible light only provides information about the closest objects in our galaxy.

    observations in different wavelengths provide different information about stars.

  • Q4

    The portion of the electromagnetic spectrum with a wavelength shorter than that of visible light that can cause sunburn is known as–

    ultraviolet radiation.

    infrared radiation.

    gamma radiation.

    microwave radiation.

  • Q5

    When comparing two waves, the wave with the greatest wavelength is the one that has–

    the most space between crests.

    traveled the longest distance.

    the greatest height.

    the greatest speed.

    Amplitude

  • Q7

    All observable objects outside our galaxy, when viewed from Earth, have their spectra shifted to slightly longer wavelengths. Astronomers have concluded that this is evidence that all objects in the universe are -

    hotter than our Sun.

    absorbing radiation from stars.

    moving away from each other.

    older than our solar system.

  • Q8

    The diagram provided gives information that relates the strength of the spectral lines of various elements, which may be detected in a star and used to predict the surface temperature of the star. Which of the following would be a reasonable prediction for the surface temperature of a star whose emission spectrum had strong silicon (Si) and magnesium (Mg) lines?

  • Q9

    The image provided is a star chart. It shows background stars that are very distant from Earth (smaller circles), as well as four stars that appear to shift positions when seen from Earth at different times of the year. Which of the four stars, based on these observations, is farthest from Earth?

    Z

    X

    Y

    W

    The wavelengths of light emitted by a star can provide information on all of the following characteristics EXCEPT–

    the number of planets orbiting the star.

    the temperature of the star.

    the direction in which the star is moving.

    the chemical composition of the star.
